LUBBICATOB.

Applicatlon'filed A'pril 11, 1925. Serial No. 22,835.

To all whom it may concern:

Be it known that I, Jnssn L. ITA N.PELT, a citizen of the United States,residing at Pullman, in Whitman County and, State of \Vashington, haveinvented certa n new and useful Improvements in Lubrlcators, .of

which thefollowlng is a specification.-

My'present invention relates to improvements in lubricators especiallyadapted for use in connection-with vehicle spring dcvices, wherein alubricant carrier is utilized to the vehicle without necessity for any Pthe vehicle. In its the device. of my invention involves the use ofalubrieant carrier in the form of a pad interposed between structuralchanges to the transverse spring and its frame bar,

whereby when the spring is depressed or comp the lubricant willbesqueezed from the carrier for distribution over the leaves of thespring for lubricating pur-.

oses. p A pair of the lubricating devices form the spring, one devicebeing located-at each side of the longitudinal center of thespring. r

In the accompanying drawings Ihave 11- lustrated one complete example ofthephysical embodiment of my inventionwherein the parts are'combined andarr d acco tothebestmodelhave'tusfar ,IIBOBSSB- devise for the practicalapplication of the. principles of my. invention.

Figure 1 is a view showing in"jtransverse section. a portion of anautomobile frame and the fr'ontjransverse sprin device, with thelubricati g device of my mvention applied thereto.

Figure 2 is the rear sprin suspension mechanism as is to i ustrate theapplicationofthe lubricating device of my invention thereto. Figure 3 isan enlarged perspective view of one of the lubricating evices.

aview showing as much of Figure 4 is a longitudinal sectional view ofone of the lubricators or lubricating devices.

For convenience in understanding the construction and operation of thedevice and the general'relation of parts I have illustrated in Figure 1a portion of a Ford automobile frame, as 1 together with the transversesuspension bar 2 which is provided with side flanges 3, depending at thesides thereof and projecting downwardly over the vehicle spring. Thetransverse suspension bar 2 is attached at its ends to the vehicle frameby means of bolts 4 and nuts 5 and these latter devices are utilized forfastening the lubricating devices to the vehicle.

The front, transversely disposed leaf spring 6 in Figure 1 is connectedas usual to the suspension bar .Z-and suspended at its ends in customarymanner above the front axle 7 In Figure 2 the rear suspending bar 8 isshown in connection with the rear spring 1 9 and the side flanges -8' ofthis arch bar roject downwardly over the central portion of theelliptical leaf spring.

A pair of the lubricators or lubricating devices is used with eachspring at the front and rear of the automobile and the lubricators arecarried at opposite sides of the longitudinal center of the springs andsecured by the bolts 4 and nuts 5 to the opposite side bars of the frame1 of theautomobile.

.In carrying out my invention I utilize a lubricant carrier 10 in theform of a pad of absorbent material, as felt, which is hereshown asfashioned of rectangular shape and designedfor insertion betweentheunder face i of the transverse suspension bar 2 or 8, and

the'top face' of one of the leaves of the.

springs fi cs9, in order that the pad may be compressed when the springis depressed or compressed. v a

The pad or carrier 10 for the lubricant, as oil, is retained in 'arectangular metal holder 11 which is clamped at one end of the .padbymeans of integral teeth or spurs 12 struck up from the metal of theholder and forced by suitable tools. or machinery into the body of thepad from its several sides.

For securing t e device in place, the holder is fashioned with anattaching plate 13 having an attaching slot 14 therein for theacoommodatio'n of one of the-bolts 4 of. the vehicle frame 1. Theattaching plate-conforms to the shape of thetransverse suspenwith whichsaid pipe communicates.

sion bar and is'fixed alongside and under said bar by the nut v5. Inattaching the plate the nut is first removed, the plate is applied inplace and slipped over the bolt 4, and thenthe nut 5 is the plate to thetransverse bar.

The supply of lubricant, as oil, is fed to the lubricating pad throughan oil feed pipe or tube 15, preferably fashioned integral with theattaching plate and extending ,filled from time to time for maintainingthe oil supply.

When the spring is compressed it will be apparent that the carrier orpad 10 is also compressed and the lubricant is forced therefrom anddistributed over the leaves of the spring for lubricating purposes.

;From the above description taken in connection with my drawings it willbe apparent that have provided a device which is comparativelyinexpensive in cost of production, but which is efficient in theperturned on the bolt to clamp supply of oil which" Having thus fullydescribed my invention what I claim as new and desire to secure byLetter Patent is I 1. In a spring lubricating device, the combinationwith a spring and its suspension bar, of a lubricating pad insertedbetween said spring and bar, a holder for the pad surrounding a portionthereof, an oil pipe connected with the holder, and means for attachingsaid lubricating device to the bar.

2. In a spring lubricating device, the com bination with a spring andits suspension bar, of a lubricating pad inserted between said springandbar, a holder'surrounding a portion of the pad and an oil pipeconnected with the holder, plate rigid with the holder, and a bolt and aslotted attaching nut for securing the slotted attaching plate to saidbar:
